Description

The Zumbrota Drivetrain RAA435-1895C-P is a remanufactured axle assembly meticulously rebuilt to the highest quality standards, offering precision and reliability for GM 12-bolt applications. This unit features an 8.875-inch ring gear and a 3.08 gear ratio, enhanced with a Posi Traction differential for improved performance and grip. The remanufacturing process begins with a thorough inspection of the axle housing for straightness, cracks, and surface wear. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by proprietary shot-peening for deep cleaning, restoring housings to their OEM finish. Internally, all components are subjected to rigorous inspection and testing. This includes the ring and pinion gears, internal gears, clutches, and carriers. To ensure optimal performance and longevity, every bearing and seal is replaced, and gears are set to the correct rolling torque using inch-pound measurements and proper backlash for quiet operation and lubrication. This axle assembly does not include hubs, brakes, backing plates, or axle shafts, which are typically sourced separately. It is built to order and ships when ready, with options for expedited shipping. A refundable core charge is applied upon purchase, which is returned upon receipt of the old, salvageable part. Specifications include an 8.875-inch ring gear size, a 3.08 gear ratio (Ratio Option GU4), and Posi Traction. The product has a shipping weight of 260.0000 LB.
